LM2596S-12规格书详情

The LM2596 /LM2596HV series operates at a switching

frequency of150 kHz thus allowing smaller sized filter compontents

than what would be needed with lower frequency

switching regulators. Available in a standard 5-lead TO-220

package with several different lead bend options, and a

5-lesd TO-262 surface mount package.

The LM2596 /LM2596HV series of regulators are monolithic

integrated circuits that provide all the active functions for a

step-down (buck) switching regulator, capable of driving a 3A

load with excellent line and load regulation. These devices

are available in fixed output voltages of 3.3V, 5V, 12V, and an

adjustable output version.

General Description

Requiring a minimum number of external components, these

regulators are simple to use and include internal frequency

compensation†, and a fixed-frequency oscillator.

A standard series of inductors are available from several

different manufacturers optimized for use with the LM2596

series. This feature greatly simplifies the design of

switch-mode power supplies.

Other features include a guaranteed ±4 tolerance on output

voltage under specified input voltage and output load

conditions, and ±15 on the oscillator frequency. External

shutdown is included, featuring typically 80 μA standby current.

Self protection features include a two stage frequency

reducing current limit for the output switch and an over

temperature shutdown for complete protection under fault

conditions.

Available in TO-220 and TO-263,TO-220B packages

(57V for HV version)

Features

3.3V, 5V, 12V, and adjustable output versions

Adjustable version output voltage range, 1.2V to 37V

±4 max over line and load conditions

Guaranteed 3A output load current

Input voltage range up to 40V

Requires only 4 external components

Excellent line and load regulation specifications

150 kHz fixed frequency internal oscillator
